▎ 摘　　要

NOVELTY - The device has a welding table (2) fixedly installed on the left end of an ultrasonic rolling welding machine (1). An ultrasonic rolling welding structure (3) is located at the upper end of the welding table (2). A material mechanism (4) is located outside the ultrasonic rolling welding structure (3). The material mechanism comprises a chemical vapor deposition (CVD) graphene copper foil (401) and a nano-copper net (402). The t chemical vapor deposition (CVD) graphene copper foil are arranged in equal distance. Tthe nano-copper net is located between two adjacent chemical vapor deposition (CVD) graphene copper foil. USE - The ultrasonic preparation device of graphene surface reinforced copper-based composite material structure is useful in ultrasonic processing technology field of copper based composite material. ADVANTAGE - The device improves the conductivity of the copper by 5-25%, has excellent graphene and high melting performance of the nanometre copper net, and limits the conductive effect of the conductive material. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for an ultrasonic preparation technique of graphene surface reinforced copper-based composite material structure. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of an ultrasonic rolling welding machine. 1Ultrasonic rolling welding machine 3Ultrasonic rolling welding structure 4Material mechanism 301Hydraulic cylinder 302Output rod 303Connection box
